Prepare your base: use Greek yogurt, low-fat milk, or a cream-and-milk mix for a dairy version, or coconut/almond milk thickened with a little cornstarch or arrowroot powder for a dairy-free version.

Infuse flavor naturally: stir in real vanilla, cacao powder, or blend in fresh or frozen fruit. Optionally simmer the base with a cinnamon stick, cardamom pods, or mint leaves for a subtle aroma.

Sweeten to taste, adding your chosen natural sweetener gradually since you can always add more.

Blend well with a high-speed blender or hand mixer until smooth, adding a frozen banana or a dollop of nut butter for extra creaminess, then freeze.
